Here's what's known, at the moment: The game is called Zelda Universe, the publisher listed with the ESRB is Nintendo, and the platform is "online." Oh, and game is rated E for Everyone.

Now, "Zelda Universe" is the name of the official Zelda website. That said, the ESRB doesn't rate web content.

At the Game Developers Conference earlier this year, Nintendo CEO Satoru Iwata made a point of mentioning that something big was being planned to mark the 25th anniversary of Zelda, so it doesn't seem too unreasonable to assume that this game has something to do with that plan.

It seems likely that Nintendo will reveal more about the game at E3 next month, especially since there has to be an actual game to show to the ESRB to receive a rating.
